Reporting Groups

Description

FluNG Group

subjects received 2 doses (1 dose per season) of FluNG vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1).

Fluarix Group

subjects received 2 doses (1 dose per season) of Fluarix™ vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1).

Number of Subjects Reporting Polymerase Chain Reaction (PCR)-Confirmed Influenza A and/or B Infection. [ Time Frame: After the first dose during the corresponding surveillance period (from mid November 2008 to the end of April 2009 (end of influenza season)) ]

Serum Hemagglutination-inhibition (HI) Antibody Titers, Against Each of the 3 Vaccine Influenza Strains, in the FluNG Groups. [ Time Frame: At Days 0 (pre-vaccination Dose 1) and 21 (post-vaccination Dose 1) of the first year (2008/2009) of the study ]

Serum Hemagglutination-inhibition (HI) Antibody Titers, Against Each of the 3 Vaccine Influenza Strains, in the FluNG Groups.

Measure Description

Vaccine strains assessed were A/Brisbane/59/2077, A/Uruguay/716/2007 and B/Brisbane/3/2007. Titers were expressed as geometric mean titers calculated on all subjects in the lot-to-lot subset of subjects.

Time Frame

At Days 0 (pre-vaccination Dose 1) and 21 (post-vaccination Dose 1) of the first year (2008/2009) of the study

Population Description

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

The One-Dose According-To-Protocol immunogenicity cohort for the lot-to-lot consistency subset included all subjects from the One-Dose ATP cohort for immunogenicity included in the lot-to-lot subset.

Reporting Groups

Description

FluNG Group

subjects received 2 doses (1 dose per season) of FluNG vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1).

Fluarix Group

subjects received 2 doses (1 dose per season) of Fluarix™ vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1).

FluNG Lot 1 Group

subjects received 1 dose of FluNG vaccine Lot 1 at Day 0 of the Year 1. They received Dose 2 at Day 0 of the Year 2, again from lot 1. The vaccine was administered intramuscularly in the non-dominant deltoid.

FluNG Lot 2 Group

subjects received 1 dose of FluNG vaccine Lot 2 at Day 0 of the Year 1. They received Dose 2 at Day 0 of the Year 2, again from lot 2. The vaccine was administered intramuscularly in the non-dominant deltoid.

FluNG Lot 3 Group

subjects received 1 dose of FluNG vaccine Lot 3 at Day 0 of the Year 1. They received Dose 2 at Day 0 of the Year 2, again from lot 3. The vaccine was administered intramuscularly in the non-dominant deltoid.

No statistical analysis provided for Serum Hemagglutination-inhibition (HI) Antibody Titers, Against Each of the 3 Vaccine Influenza Strains, in the FluNG Groups.
